The invention embraces such embodiments of the disclosed ideas as fallwithin the scope of the appended claims.

I claim:

1. A lamp comprising a shell having a rim, a circular lens fitting saidrim and having a flange underlying said rim and substantially in theform of an ellipse circumscribing the circle of said lens, and springmeans within said shell urging said lens outwardly through said rim andalso urging said flange against said rim.

2. A lamp comprising a shell having a rim, a lens fitting said rim andhaving a flange underlying the same, a reinforcing liner for said shell,a lamp support rigidly mounted on said liner, and spring means on saidliner engaging said lens.

3. A lamp comprising a shell having a window in one end and a lateralwindow intermediate its ends, said end window having a lens with aflange engaging a rim of said shell, a reinforcing liner for theopposite end of said shell having an extension reinforcing the side ofsaid shell opposite said lateral window, and spring means on saidextension engaging said lens.

4. A lamp comprising a shell having a window in its larger end and alateral window intermediate its ends, a reinforcing liner substantiallylining the smaller end of said shell, one side thereof extending towardthe larger end and substantially lining the side of said shell oppositesaid lateral window.

5. A lamp comprising a shell having a window in one end, and a lateralwindow intermediate its ends, a reinforcing liner for said shell, atransverse plate secured to said liner adjacent said lateral window, anda lamp socket mounted on said plate.

6. A lamp comprising a substantially conoidal shell having a coaxialwindow in its larger end and a lateral window intermediate its ends, a

reinforcing liner for said shell comprising a cup substantially liningthe smaller end of said shell and having an extension substantiallylining the remaining side of said shell opposite said lateral window, atransverse plate having a peripheral flange secured to said cup adjacentsaid lateral window, said plate having a flanged opening, and a lampsocket mounted in said opening.

'7. A lamp comprising a shell having a window in one end thereof, areinforcing liner substantially lining the other end of said shell, alamp support secured to said liner, said liner having threaded internalbosses and said shell having registering apertures, and screws passingthrough said apertures and engaging said bosses for supporting thewhole.

8. A lamp comprising a shell having a lateral aperture, a lighttransmitting closure therefor, a reinforcing liner substantially liningone end of said shell and having an extension substantially lining theside of said shell opposite said lateral window.

9. A lamp comprising a shell having a lateral aperture, a lighttransmitting closure therefor, a reinforcing liner substantially liningone end of said shell and having an extension substantially lining theside of said shell opposite said window, and means cooperating with saidextension and engaging said closure for holding it in position withrespect to said aperture.

10. A lamp comprising a substantially conoidal shell having a rim, alens having a flange fitting said rim, said shell having a lateralaperture, a light transmitting closure for said aperture, a'reinforcingliner for said shell comprising a cup substantially lining the smallerend of said shell and having'an extension substantially lining theremaining side of said shell opposite said lateral window, a transverseplate marginally secured to said cup adjacent said lateral window, alamp socket mounted on said plate, and springs on said liner extensionurging said flange against said rim.
